This paper critically analyzes the deconstructive tendency that some authors have shown against the so-called Metaphysics of Exodus, promoted by philosophers such as Étienne Gilson. The most original notion in Thomas Aquinas’s philosophy is that being (esse) is said to derive not from the Bible as Gilson claims, but from Neoplatonic sources of pagan ambience, such as the author of the De causis (Proclus) or the Dionysius Areopagite. We carry out an analysis of the status quaestionis by showing, contrary to (...) the critics of the ‘Metaphysics of Exodus,’ that this deconstructive tendency is unfounded and untenable. (shrink)
